Giix Crud

Hi everyone,
I'm using GIIX for CRUD operations on tables.
is not well documented so I have a lot of doubts.

i'm using an example to explain my problem:

we have these tables

ARTICLES
article_id | title | description | author_id

AUTHORS
author_id | name | etc...

How can I use GIIX, automatically, to generate a CRUD for the ARTICLES table that for insertion and search operations, instead of using a text input for author_id, give me a dropdown list with the names of authors?

Sorry for my English

Thanks,

lilli
